What You Need to Grow Microgreens Indoors

Head to your local garden store to find what you need to grow microgreens indoors.

You’ll want:

  • Tray (anything works, from seed starting trays to aluminum pie tins)
  • Larger tray to hold the other and catch water drainage
  • Trowel (optional)
  • Seed-starting soil mix
  • Watering can
  • Seeds
  • Blackout dome, humidity dome, or plastic wrap
  • Spray bottle

 

How to Grow Microgreens Indoors

  1. If your tray doesn’t have drainage, poke some holes in it.
  2. Fill the tray with 1 to 2 inches of soil, using the trowel, if desired. Place the tray in another larger tray to catch any water that drains out. Then take a watering can and thoroughly dampen the soil.
  3. Scatter the seeds over the soil. While you don’t want to completely cover the soil with seeds, go ahead and be pretty generous here.
  4. Cover the seeds with a very thin layer of soil. (But read the seed label. Some seeds call for a thicker top layer of soil.)
  5. Using a watering can, water the seeds again until they’re nice and damp but not drowning.
  6. Cover the seeds with a blackout dome or humidity dome, which you can find in gardening stores. (You can also use plastic wrap.)
  7. Place the tray in direct sunlight and leave the seeds covered for about two days, misting with water from a spray bottle when needed, says Hailey Bernal, manager of customer service for True Leaf Market. Typically this means misting once or twice a day so the soil doesn’t dry out. (But you never want to overwater either.)
  8. Once leaves appear, take off the blackout dome, Bernal says. She recommends keeping the soil moist by bottom watering twice a day. To do this, you pour water into the larger tray (the one holding the tray with the microgreens planted in it) so the soil soaks up that water. Then drain off any excess water. As an alternative, you can continue to mist the greens with water.

 

How to Harvest Microgreens

After about 10 days, your microgreens will be ready to harvest, Bernal says. Gently grab a bunch and, with your other hand, snip the greens off just above the soil level with scissors. Wash thoroughly and dry.

It’s best to use the microgreens immediately. However, you can keep extra in the refrigerator by wrapping them in a paper towel and placing in an airtight container. Once harvested, microgreens will not grow back. However, you can compost the soil then plant new seeds.

 

The Best Microgreens to Grow

Some of the best microgreens to grow are sunflower, arugula, kalebroccoliradish, pea, and basil, Bernal says. These not only have great flavor, they’re also nutritious and super easy to grow.

Microgreens contain micronutrients such as potassium, iron, zinc, magnesium, and copper, says nutritionist Keri Gans, RDN, author of The Small Change Diet. She adds that they also contain polyphenols, which have antioxidant properties.
